A Fracture or a Sprain: What's The Difference?
In traumatology, two injuries are among the most common: a fracture and a sprain. We all know someone who’s gone through one of these two circumstances, or perhaps we’ve even experienced them ourselves.
Because they’re such common injuries, it’s logical that they lend themselves to confusion. When faced with a trauma that produces, swelling, and weakness in a limb, asking whether we’re dealing with a fracture or a sprain is a valid question.
The truth is that they’re not the same thing and neither are their consequences. A fracture is more serious, although there are also really serious sprains that put joints at risk. These can negatively affect a person’s work, athletic abilities, and lifestyle.
We must first clarity that a sprain is typically a ligament injury. In this case, the ligaments involved are stretched more than they should be and can’t return to their natural position. In extreme situations, a sprain can involve a ruptured ligament.
On the other hand, a fracture is a bone injury. That’s to say, the bone tissue is interrupted, cut, or deeply injured.
Let’s take a closer look.
From a sprain to a fracture
Although the doubt about having suffered a fracture or sprain is valid, many believe that the former is a consequence of the poor treatment of the latter. This is not the case. They’re separate entities that aren’t part of the same injury process.
Instead, we can say that there are degrees of severity in these injuries, and in that sense, we can mark a gradation from the mildest sprain to fracture. Again we reiterate, it’s not because one leads to the other, but because of their different severity.
Thus we would have:
- First-degree sprain: This is the mildest. The ligaments have stretched a little and cause pain. There may be some swelling in the affected joint and fluid accumulation (edema). Treatment with rest and taking an anti-inflammatory drug is sufficient.
- Second-degree sprain: Here, the ligament strain is slightly greater than the previous degree. There are also some small breaks in the fibers. Kinesiology sessions are necessary for recovery.
- Third-degree sprain: This is the most severe form of a sprain. The ligaments are cut, not only stretched. It requires more intensive treatment with strict rest, movements with a support brace, and occasional physiotherapy exercises.
- Simple fracture: This is the breakage of the bone that remains inside the body. It may or may not be accompanied by a nearby sprain due to the same trauma that caused the fracture.
- Exposed fracture: The bone tissue is broken and part of it is exposed outside of the body through a wound in the skin. The bone is in contact with the external environment.

Differences between the two injuries
To differentiate between a fracture and a sprain, we need to consider the symptoms, how the trauma occurred, and how the affected area was left after the trauma. The movements that are possible once the injury occurs are usually indicative of the severity.
However, as soon as the injury takes place, they can be easily confused, since they share symptoms. Both cases begin with intense pain and swelling. The area becomes inflamed by the same process that the injured body unleashes and by the accumulation of liquid due to those structures that stretch and break inside.
With hematomas, the situation is more complex. In general, fractures present hematoma and most sprains don’t. But bruising does occur in severe sprains, and there may also be a fracture that doesn’t show bruising on the surface of the skin.
A key sign of fracture is marked deformity of the injury site. The broken bone causes skin elevations that result in functional impotence. It is very difficult to move a fractured bone.

First aid for fractures and sprains
Once the injury has been determined as a sprain, the steps to follow to provide first aid at the scene would be:
- Immobilization: The sprained joint should be kept still.
- Localized cold: Apply cold to the joint reduces inflammation and thus reduces pain.
- Bandaging: Tight or compressive bandaging is very useful in sprains. Besides favoring immobilization, the bandage controls inflammation.
- Elevating the extremity: Since we don’t want more fluid to accumulate in the damaged joint, we must elevate it so that it drains the excess edema.
On the other hand, if the injury is identified as a fracture, the first aid would be:
- Touch as little as possible: It’s not the same as a sprain and you can’t manipulate a broken bone carelessly. Rather, you must isolate the area of the injury, avoiding contact.
- Promote circulation: If the injured person suffered a fracture in an extremity and has an object that can interrupt the blood flow, try to remove it. For example, if the person has a fractured wrist and wears a watch, then they must try to remove the watch, touching the affected area as little as possible.
- Control bleeding: If there’s bleeding next to the fracture, the doctor must compress the point where the blood comes out. Large and exposed fractures are capable of causing abrupt blood loss that can jeopardize the recovery of a limb.
As you can see, there are many differences between fractures and sprains, even though they may present similar initial symptoms. It’s important to get an accurate diagnosis from a doctor, as treatment depends on it.It might interest you...
